Two young starters go down in Week 2

Week 2 produced a jolt: Chicago’s Caleb Williams exited with a non-contact hamstring injury, and Washington’s Jayden Daniels suffered a left-elbow dislocation after an awkward fall. Both injuries were documented in CBS Sports’ Monday reporting and became part of the league’s early-week news flow.

Chicago’s initial description, per reporting, is cautious — Williams will undergo more testing and was characterized as "week to week" — while Daniels’ elbow event immediately raised the specter of a longer absence because it is a recurrent injury.

What the injuries mean — short term

This is an immediate availability problem for both teams. A hamstring for a mobile quarterback tends to limit designed runs and scramble ability while the player heals; teams typically manage workload and reintroduce movement gradually.

An elbow dislocation on a quarterback’s throwing side is a different animal: aside from pain and immobilization, it can leave instability that affects velocity, accuracy and endurance of the arm. CBS’ reporting notes this is Daniels’ second left-elbow dislocation in roughly 11 months, which increases concern about recurrence and the risk that Washington must turn to contingency plans.

Why it matters for the season and what to watch next

Beyond the immediate question of missed games, the two injuries change how opponents will game-plan and how the affected teams might set short-term goals. The NFL’s Week 3 power rankings already reflect how volatile early-season perceptions can be: sudden injuries and unexpected wins reshuffle narratives and expectations.

Concrete things to watch in the coming days: official imaging and team medical updates; whether either team elevates a veteran or leans on a previously underused backup; and how play-calling adjusts if mobility or throwing strength is curtailed. Teams have little margin for error when the season is young, so early injuries can have outsized consequences.

Bottom line

Both injuries are consequential, but the timeline and long-term implications likely diverge. Williams’ hamstring is serious — and measurable in weeks — but tends to be more straightforward to manage than a recurrent throwing-arm elbow problem. Daniels’ history with the same elbow makes his situation a higher-risk medical and roster challenge for Washington.

Expect daily updates. This is developing: imaging, specialist evaluations and team decisions over the next week will determine how each franchise navigates the immediate stretch of the schedule.

SLAM Explains

The complicated part, made simple.

Why a hamstring pull and an elbow dislocation are different kinds of problems

A hamstring strain primarily affects a player's ability to accelerate, plant and scramble — mobility and sudden speed. An elbow dislocation directly impacts the throwing mechanism and can involve ligament damage, instability or nerve issues that complicate rehab.

Why it matters here

The hamstring injury can often be managed with graded return-to-play protocols that preserve throwing mechanics; an elbow dislocation to a quarterback's throwing arm can require a longer, more cautious timeline and raises re-injury risk.
